The amount of times shrink_slab is called is completely unpredictable. Changing the size of cached data structures is a lot more likely to change this than this shrinker change, for instance. Not to mention, the amount of times shrink_slab() is called is not changed directly here. But rather, the amount of times an individual shrinker actually does work. _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/containers
